Langevin equations for the run-and-tumble of swimming bacteria
(Royal Society of Chemistry, 2018-05)
The run and tumble motions of a swimming bacterium are well characterized by two stochastic variables: the speed v(t) and the change of direction or deflection x(t) = cosφ(t), where φ(t) is the turning angle at time t. ...
In-cylinder flow control in a 4-valve spark ignition engine: numerical and experimental steady rig tests
(Professional Engineering Publishing Ltd, 2011-06)
Computational fluid dynamic (CFD) simulations and experimental steady
flow tests (flow discharge, swirl, and tumble) were carried out to study
the in-cylinder flow in a commercial four-valve spark ignition engine.
The ...
Run-and-tumble bacteria slowly approaching the diffusive regime
(American Physical Society, 2020)
The run-and-tumble (RT) dynamics followed by bacterial swimmers gives rise first to a ballistic motion due to their persistence and later, through consecutive tumbles, to a diffusive process. Here we investigate how long ...
Coarsening and clustering in run-and-tumble dynamics with short-range exclusion
The emergence of clustering and coarsening in crowded ensembles of self-propelled agents is studied using a lattice model in one dimension. The persistent exclusion process, where particles move at directions that change ...
Penetration of hydrolysed soy protein-added brine and its effect on yield and pH of beef steaks from the biceps femoris muscle
(ELSEVIER SCIENCE BV, 2011)
This study was aimed to evaluate the penetration behaviour of different brines with tumbled beef steaks from the biceps femoris muscle, specifically their interactions with pH and effects on yield. Six muscles from different ...
A stochastic model for directional changes of swimming bacteria
(Royal Society of Chemistry, 2017-04-17)
In this work we introduce a stochastic model to describe directional changes in the movement of swimming bacteria. We use the probability density function (PDF) of turn angles, measured on tumbling wild-type E. coli, to ...
